Charles Charles Eastman was a young Dokota physician who went to Dartmouth College and Boston University. In 1890 he moved his practice as a physician to the Pine Ridge reservation in western South Dakota. His was part of Wahpenton and Mdewakanton Dakota tribe rather than Oglala Lakota and took pride in being Native. Upon his arrival‚ he experienced a disastourous dust storm and later would come across the aftermath of a massacre. The massacre was due to altercations of warfare on the northern

Epoxidation Reactions Lab Report 2 Abstract An oxygen atom is transferred from a peroxy acid to the carbon=carbon double bond thus forming an epoxide. Scheme 1. Oxone Epoxidation. Scheme 2. mCPBA Epoxidation. The percent yield for the Oxone epoxidation reaction was 65% yield and the mCPBA epoxidation reaction was 70% yield. Oxone is the greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic

The shooter was a teenager that loved playing violent games and was not a very outspoken person; he hardly talked to his classmates. Many segments of society such as professors‚ sociologists‚ and psychologists are developing studies to try to find the answer for this question. The channel called Video Games and

Aim: To determine a value for the spring’s force constant‚ k. Introduction: Hooke’s Law indicates the relationship between the amount of extension‚ e‚ of a spring to the size of the force‚ F‚ acing on it. This relationship may be written as :- F = ke F = ke where k is a constant for which particular spring you are using. It is the force constant of the spring. * The force applying on the spring‚ F‚ is denoted by Newton in SI Units. (N) * The amount of extension of the spring

Introduction An atom is the smallest part of an element that can take part in a chemical change. The word “atom” comes from the Greek “atomos”‚ which means “unable to be cut”. Atomism is the philosophy of the existence of atoms. The first theories of atoms come from India. There was a Hindu sage named Kanad that hypothesized that all mater was composed of earth‚ water‚ light‚ wind‚ ether‚ time‚ space‚ mind and soul. Then another philosopher named Pakuda Katyayana suggested that everything can be

Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often
